The Bean (Phaseolus vulgaris) Flower and Fruit:
What has become of the various parts of the flowers during development of the fruit?
How many locules are there in the ovary you are examining?
What has become of the various floral parts during development of the fruit?
Ans:
Fruit is a fertilized mature part of ovary. The fruit of Phaseolus vulgaris is dry dehiscent legume type. During the development of fruit, the different part of flower become change in the following ways
Calyx = persistently present with the stalk of fruit.
Corolla = disappear
Stamen = not present during fruit development, produce pollen from which the male gametes produce seed with egg.
Carpel:
Style and stigma = not present
Ovary wall = dry pericarp
Ovule = edible seed
Nucellus = Perisperm
Outer intigument = testa
Inner intigument = tegment
Micropyle = micropyle
Funicle = staked of seed
Hilum = hilum
The number of locule or chamber in the ovary of Phaseolus vulgaris is one. Phaseolus vulgaris is a plant of the family leguminoceae with marginal placentation and the ovary has one chambered or locule with one ovule in each locule.
